A technique for audio encoding is provided. According to an example embodiment, the technique comprises deriving a first quantization error that is descriptive of an error resulting with a non-predictive quantization of an audio parameter of an audio signal segment, deriving a second quantization error that is descriptive of an error resulting with a predictive quantization of said audio parameter of said audio signal segment, determining whether said second quantization error exceeds said first quantization error by at least an adaptive margin that is dependent on the number of consecutive audio signal segments that precede said audio signal segment in which said audio parameter is provided quantized with said predictive quantization, providing said audio parameter of said audio segment quantized with said non- predictive quantization as part of an encoded audio signal at least in case the outcome of said determination is affirmative, and providing otherwise said audio parameter of said audio segment quantized with said predictive quantization as part of an encoded audio signal. |
